"Whereas SQUARE INCH FIELD was composed largely in the camera, Rimmer's next film, MIGRATION, made full use of rear-projection rephotography, stop-framing, and slow motion. The migration of the title is interpreted as the flight of a ghost bird through aeons of space/time, through the micro-macro universe, through a myriad of complex realities. A seagull is seen flying gracefully in slow motion against a grainy green sky; suddenly the frame stops, warps and burns, as though caught in the gate of the projector. Now begins an alternation of fast and slow sequences in which the bird flies through time-lapse clouds and fog and, in a stroboscopic crescendo, hurtles into the sun's corona. Successive movements of the film develop rhythmic, organic counterpoints in which cosmic transformations send jelly fish into the sky and ocean waves into the sun." - Gene Youngblood.
